We look at the division of 400638 by 449 
Let's see how many times 449 fits into 400638.

Advancing to step 1:
449 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 449

On to step 2:
When dividing 40 by 449, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 449

Going ahead to step 3:
449 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 400, we get 400.
Take the next digit (6) from the dividend and append it to 400, then repeat: 4006 / 449

Going ahead to step 4:
If we divide 4006 by 449, we get 8 and a remainder of 414.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 3592 from 4006 leaves us with 414.
Append the next digit (3) from the dividend to 414 and continue with: 4143 / 449

Going ahead to step 5:
If we divide 4143 by 449, we get 9 and a remainder of 102.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 4041 from 4143 leaves us with 102.
Bring next digit (8) of the dividend behind the 102 and repeat the process: 1028 / 449

Moving on to step 6:
449 goes into 1028 2 times with a remainder of 130.
Put 2 as the next digit of the answer. 
Result so far: 892.0
The remainder is 130 after subtracting 898 from 1028.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 7:
449 goes into 1300 2 times with a remainder of 402.
The next digit of our result is 2. 
Result so far: 892.2
Subtract 898 from 1300 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 8:
449 goes into 4020 8 times with a remainder of 428.
Write down 8 as next digit of the result. 
Result so far: 892.28
If we subtract 3592 from 4020, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 9:
If we divide 4280 by 449, we get 9 and a remainder of 239.
Record the quotient 9 as the next digit in the result. 
Result so far: 892.289
If we subtract 4041 from 4280, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 10:
2390 divided by 449 is 5 with a remainder of 145.
The next digit of our result is 5. 
Result so far: 892.2895
The remainder is 145 after subtracting 2245 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 11:
If we divide 1450 by 449, we get 3 and a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 892.28953
If we subtract 1347 from 1450, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 12:
449 can be fit into 1030 2 times, resulting in a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 892.289532
Subtracting 898 from 1030 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 13:
1320 divided by 449 is 2 with a remainder of 422.
Record the quotient 2 as the next digit in the result. 
Result so far: 892.2895322
The remainder is 422 after subtracting 898 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

The quotient of the division is 892.2895322, and the remainder is 4.22e-06.
